Given numbers are 642,204,773,126,698
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,204,773,126,698 is 123662539476.
Find LCM of 642,204,773,126,698 with Prime Factorization
2 | 642, 204, 773, 126, 698 |
3 | 321, 102, 773, 63, 349 |
107, 34, 773, 21, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 34 x 773 x 21 x 349 = 123662539476
Therefore, the lowest common multiple of 642,204,773,126,698 is 123662539476.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
642 x 204 x 773 x 126 x 698 = 8903702842272
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
642 : 1, 2, 3, 6, 107, 214, 321, 642
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
773 : 1, 773
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
698 : 1, 2, 349, 698
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,204,773,126,698, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
204:2x 2x 3x 17
773:773
126:2x 3x 3x 7
698:2x 349
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3 = 72
Therefore, the value for common factors is 72.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 8903702842272/(1x72)
LCM = 8903702842272/72
LCM = 123662539476
Thus, we can understand that the LCM of 642,204,773,126,698 is 123662539476.
